Hi all,

finally tore down my dishwasher today after getting sick of doing
dishes by hand and striking out on Craigslist. For those of you that
missed the first installment, a transformer exploded a couple streets
over late Sunday night or early Monday morning and blowed up some
stuff in my house (a surge strip, an electrostatic air filter, and my
dishwasher.) I've already ordered (online) a new power supply for the
air filter, and replaced the surge strip and the TVSS breaker that
was in my main panel (the "protected" light was out on one leg.)

Turns out that the failure of the dishwasher looks exactly like the
failure of the air filter; on the power supply board there is a
orangeish-yellow dsc-shaped component soldered onto the board about
1/2" in diameter, and it appears to have failed with extreme
prejudice. Am I correct in assuming that this is a MOV? Could I
just do a component level repair of this rather than replace the
whole board? I really hate this dishwasher and don't want to spend a
lot of money on it. If this is a MOV, is value important, or simply
"bigger is better?" I'm sorry for the dumb questions, but I'm not
particularly electronically knowledgeable (made it through two EE
classes in college and I think I've forgotten most of what I learned)
just trying to get this back up and running. If Trible's had still
been open by the time I got it apart, I probably wouldn't be asking
the question, but if there's a chance I could fix it today...


It could be a ceramic disk capacitor.

Does it SAY anything on the component ("MOV" would be a clue, so would ".01
mfd")
